computer port. In the administration of mnemonic dialing, one table that cross-references mnemonic
names to telephone numbers is created and maintained on the switch.
Data Call Setup From a Voice Terminal
This features lets users dial the data endpoint from a voice terminal with an associated data module. This
feature must be used in lieu of Terminal Dialing to establish connections for synchronous (for example,
IBM 3274) terminals that do not have an RS-366 automatic calling unit (ACU) interface.
Computer Dialing
This feature makes it possible for a host computer to automatically dial a data endpoint. Hosts can
originate data calls when their ports are equiped with data modules or modems that have an ACU. The
hosts must also have software that manages call initiation and termination.
Data Hot Line
With this feature, the switch automatically dials a default number when the user presses the BREAK key at
the terminal or the Originate/Disconnect bottom on the data module. This feature is an administrable
option.
